Fuel Gas Supply System (FGSS) is used to supply fuel gas for ME-GI engines.
LNG that is being supplied from RV/FSRU (combination of LNG Tanker, Re-gasifi cation facility and Gas unloading facility) by HP LNG Pump, is vaporized by HP Vaporizer. The seawater is utilized as a source of heat that vaporizes LNG, and also if the seawater temperature drops, it will be heated by the Seawater Heating System. In such case, DongHwa Entec’s Seawater Heater may be used.
E.S.S. (Energy Saving System) is an intelligent control system to optimize the central seawater cooling system of a ship. This system’s sensor measures the temperature of seawater and clean water as well as the opening and closing locations of 3-way valves and supplies the optimized energy to central seawater cooling pumps of ships at sea.
Based on its long-accumulated technologies, the company has acquired international certifi cations such as ISO 9001 and 14001, CE and GOST.
